Answer:
What can be noticed about the ligands and their receptor is that the configuration of both coincide, as a key would with its lock, which demonstrates the specificity of a receptor by its ligand.
Explanation:
A <u>ligand</u> corresponds to a molecule considered a signal or a messenger, while the <u>receptor</u> is a protein on the cell surface, with the capacity to accept a ligand.
Ligands and receptors constitute pairs that complement each other, so that <u>each receptor can bind to a specific ligand</u>, similar to what happens with a key and a lock.
Once the ligand-receptor complex is formed, changes occur inside the cell, which define a certain effect.
A pedigree is a symbolic diagram that is used to show the presence and presentation of specific alleles in the families of both parents. This is used mostly for genetically controlled diseases and conditions. If a couple is in genetic counseling a pedigree is valuable in helping to determine the risk of that couple having a child that will either present with the condition or be a carrier for the condition. A pedigree is also composed in a way, with shapes and colors, that is an easy to understand visual representation of the inheritance patterns.
Answer:
The two chromosomes in a homologous pair are very similar to one another and have the same size and shape. Most importantly, they carry the same type of genetic information: that is, they have the same genes in the same locations. However, they don't necessarily have the same versions of genes.

Rapid environmental changes can cause:
1) Species can become vulnerable to extinction.
2) A decrease or increase of populations.
3) Diversity of species.
